Abstract
In a RC-IGBT chip, an anode electrode film and an emitter electrode film are arranged with a distance therebetween. The anode electrode film and the emitter electrode film are electrically connected by a wiring conductor having an external impedance and an external impedance. The external impedance and the external impedance include the resistance of the wiring conductor and the inductance of the wiring conductor.
